My Lords, it is a great pleasure to follow the noble Baroness. I do not entirely agree with her but I thought that she put her points in a very pithy way. Clearly the trade-offs between the benefit of HS2 in environmental terms and some of the environmental defects are those that always have to be weighed. The problem that I have is that sometimes we weigh these balances for so long that in the end we make too little progress.
My frustration, which I share with other noble Lords, is that this country is so bad at major infrastructure projects, yet in HS1 we have an example of a brilliant project that I think was undertaken on time and on budget without one major health and safety victim. It is unbelievable that we are spending so many years building what is still a relatively short piece of track. There have been many reviews of major infrastructure projects in this country—my noble friend has looked into this matter on a number of occasions—but, given our economy and the challenges that we face, we cannot afford to mess around any longer with these critical infrastructure projects.
There are obviously questions to be answered about HS2. We have heard about the cost and delay overruns. The noble Lord, Lord Teverson, raised the issue of whether there was overspecification in the original project, which the review will no doubt look into. Like my noble friend Lord Adonis, I think the Minister put the case for HS2 extremely persuasively and, essentially, I want to endorse what she said. I also wanted to touch briefly on the impact on the economy of Birmingham and the West Midlands, about which I am most informed.
Just looking at the capacity crisis on our railways, it is a no-brainer that we have to increase capacity one way or another. Whatever the cost overruns on HS2, the capacity issue simply will not be washed away. If, for instance, the review suggested that HS2 should be cancelled, or in the end the Government decided to do this, they will still be left with this incredible capacity issue. What are the alternatives? One is to four-track the west coast main line between Rugby and Wolverhampton, but the cost and disruption would be enormous. The same would be said if the Chiltern line from London to Birmingham was changed to a four-track line. That is clearly another option, as is turning trains into double-deckers. This is feasible, but bridges would have to be raised and services would be disrupted for a very long time and at huge cost. So what are the alternatives? In the end, the review is bound to conclude that there is no alternative to carrying on with HS2.
My noble friends Lord Adonis and Lord Snape made the point that construction has started. A huge number of jobs have already been created in Birmingham and the West Midlands and the National College for High Speed Rail has been established. A huge amount of investment is taking place in the city of Birmingham on the strength of HS2. The West Midlands economy is fragile. The potential of Brexit and the damage it could do to our motor industry is immeasurable. Cancelling HS2 at the same time as we face these huge uncertainties would have a devastating impact on our economy. The noble Lord, Lord Greaves, rightly referred to those who are talking to the Government. Our own Select Committee looked at this and focused on the railway challenges facing the north of England. I sympathise with noble Lords who are concerned about the railway infrastructure in the north of England, but I do not think that stopping the London to Birmingham part of HS2 and starting again in the north is a rational or sensible approach to delivering this railway.
I want to thank the Minister, who has my full support for this Bill. We will attend it with great interest at some point in the future—maybe the distant future. I want to say to the Government that this was a convenient way to get HS2 off the election agenda, but in the end, they will have to make a hard decision. From all the Minister has said, I think she knows already that the only decision that can be made is to continue with HS2. I very much hope that she will do that.
